Fire Safety & Security Products

Characteristics

Environmental

– ecologically processing

– recyclable materials

– electronic and synthetic material simply separable

Characteristics

– resistant to environment and interference factors such as dust, fibers, insects, humid-

ity, extreme temperatures, electro-magnetic interference, corrosive vapors, vibration

– insensitive to impact, tamper protection

– protected electronics, high-quality components

– integrated short-circuit isolator, which locate the defective part on the detector bus of

the control unit and insulates between 2 detectors

– built-in alarm indicator (AI), visible at 360°

– up to 2 external alarm indicators of type DJ1191/DJ1192 connectable per detector

– signal processing with detection algorithms

– automatic address allocation during commissioning

– the same detector base type can be used for each detector type, for surface and re-

cess supply wiring

Optional accessories

– Detector locking device LP720 as protection against theft

– Designation plate FDBZ291

– Detector base seal RS720 for higher protection category

– Micro terminal DBZ1190-AA (0.28… 0.5 mm2)

– Connection terminal DBZ1190-AB (1.0… 2.5 mm2)

– Sounder base DBS720

OH720 Multi-sensor smoke detector

Multi-sensor smoke detector consist of:

–

Detector

–

Dust cap to cover the detector for protection against dust during construction work

Function

–

works according to the scattered light principle with one sensor, optical forward

scattering

–

Opto-electronic sampling chamber holds off disturbing extraneous light but opti-

mally detects smoke particles

–

an additional heat sensor increases the fire detector’s immunity to deceptive phe-

nomena

–

selectable detection behavior by different parameter sets

–

immunity against transient false alarm causes

Application

–

for the detection of flaming fires caused by the combustion of liquid and solid mat-

ters, as well as smoldering fires

–

for reliable fire detection in environments with deceptive phenomena
